Description

Technical Field

[0001] The utility model belongs to the technical field of door and window accessories and relates to a door and window drainage hole cover. Background Art

[0002] Doors and windows can be seen everywhere in daily life. On rainy days, water will accumulate on the lower frames of doors and windows. If the rainwater cannot be discharged to the outside in time, the rainwater may enter the room or soak the doors and windows. Therefore, drainage holes are generally provided in the lower frames of existing doors and windows, and drainage hole covers are provided on the drainage holes to discharge the rainwater on the lower frames of doors and windows to the outside in time.

[0003] For example, a Chinese patent document discloses a mosquito and sandproof drain hole cover for thermal insulation aluminum alloy system doors and windows (application number: 201820301431.5), which includes a drain hole cover and a baffle. The drain hole cover is installed on the drain hole of the thermal insulation aluminum alloy system doors and windows. A baffle is provided in the drain hole cover. A rotating shaft is fixedly connected to the top of the baffle. The ends of the rotating shaft extend beyond the two sides of the baffle, and the rotating shaft is placed on supporting claws protruding from the drain hole cover to realize the hinge connection between the baffle and the drain hole cover. A plurality of claws are also fixed in the drain hole cover, which extend from the drain hole cover. The drain hole cover is detachably mounted on the drain hole of the thermal insulation aluminum alloy system doors and windows through the claws.

[0004] The heat-insulating broken bridge aluminum alloy system door and window anti-mosquito and wind-sand drain hole cover has the following shortcomings during use: the drain hole cover is connected to the edge of the door and window drain hole only by two narrow and thin claws, resulting in poor connection stability between the drain hole cover and the door and window frame, and is easy to fall off and drop. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to provide a door and window drain hole cover. The technical problem to be solved by the utility model is how to improve the connection stability between the drain hole cover and the door and window frame.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A door and window drainage hole cover comprises a plate-shaped cover body, characterized in that the inner side of the cover body has a block-shaped mounting portion, the middle part of the mounting portion has a main claw extending in a direction away from the cover body, the two sides of the mounting portion have auxiliary claws respectively, the bottom of the mounting portion is provided with a water diversion groove upward, and the cover body is provided with a plurality of drainage holes connected to the water diversion groove along its length direction.

[0008] The mounting portion of the present door and window drain hole cover is block-shaped as a whole, so that the mounting portion accounts for a large proportion and has great structural strength. At the same time, the middle portion of the mounting portion has a main claw extending in the direction away from the cover body, and the two sides of the mounting portion have auxiliary claws. On the one hand, the block-shaped mounting portion can limit the deformation distance of the auxiliary claws on both sides thereof, thereby improving the reliability of the connection between the auxiliary claws and the door and window frames. On the other hand, the main claw and the auxiliary claw form a multi-point clamping fit with the door and window frames, thereby improving the connection stability between the drain hole cover and the door and window frame. In addition, the water diversion groove and a plurality of drainage holes connected to the water diversion groove opened along the length direction of the cover body can enable the water flow in the door and window frames to be discharged to the outside better and faster.

[0009] In the above-mentioned drain hole cover for doors and windows, the top of the mounting portion has a protrusion for clamping. The protrusion can further increase the clamping points between the drain hole cover and the door and window frame, thereby improving the connection stability between the drain hole cover and the door and window frame.

[0010] In the above-mentioned drain hole cover for doors and windows, there are two protrusions, which are respectively arranged adjacent to the two auxiliary claws. The protrusions of the above-mentioned structure can maintain the symmetry of the drain hole cover structure, thereby improving the connection stability between the drain hole cover and the door and window frame.

[0011] In the above-mentioned door and window drain hole cover, a baffle facing the drain hole is arranged in the water guide groove, and the baffle can swing between the main claw and the cover body. By arranging the baffle in the drain hole, when the external wind force is strong, the baffle is kept in a vertical position to prevent the wind from blowing into the room, and also to prevent insects from crawling into the room, thereby playing a role of windproof and insect-proof. At the same time, when there is a lot of water in the door and window frame, the water flow can flush the baffle, causing the baffle to swing toward the cover body, so that the water flows faster to the drain hole for discharge.

[0012] In the above-mentioned door and window drain hole cover, there is a stop block in the water diversion groove, the height of the stop block is less than the height of the baffle, and when the baffle swings toward the cover body, the baffle can lean against the stop block in an inclined state. By setting the stop block, it is prevented that the baffle lies flat and leans against the top wall of the water diversion groove under the impact of the water flow and cannot be reset, so that when the baffle swings toward the cover body, the baffle can lean against the stop block in an inclined state to better allow water to pass through and discharge, and then the baffle can swing toward the main claw to reset. At the same time, the height of the stop block is less than the height of the baffle, so as to prevent the stop block from blocking the path of water flowing to the drain hole, so as to ensure the drainage effect.

[0013] In the above-mentioned door and window drain hole cover, the stop block is in the shape of a long strip and extends along the length direction of the cover body, and the two ends of the stop block are respectively connected to the inner wall of the water diversion groove. The stop block of the above-mentioned structure is convenient for one-piece molding and manufacturing, and at the same time, it can better provide abutment for the swinging baffle.

[0014] In the above-mentioned drain hole cover for doors and windows, a clearance gap is provided on the side wall of the water channel opposite to the drain hole. After the drain hole cover is installed, the clearance gap allows more water in the door and window frame to flow into the water channel. At the same time, when there is a lot of water in the door and window frame, the water flow can better break the baffle and flow to the drain hole for faster discharge.

[0015] In the above-mentioned door and window drain hole cover, the two sides of the top of the baffle plate have rotating shafts, the groove wall of the water diversion groove has two mounting holes, and the two rotating shafts of the baffle plate are respectively inserted into the two mounting holes. The matching structure of the rotating shaft and the mounting hole is simple, the processing is convenient, and the swing effect of the baffle plate is guaranteed.

[0016] Compared with the prior art, the advantages of the present door and window drain hole cover are: the mounting portion of the present door and window drain hole cover is block-shaped as a whole, so that the mounting portion accounts for a large proportion and has great structural strength; at the same time, the middle part of the mounting portion has a main claw extending in the direction away from the cover body, and the two sides of the mounting portion have auxiliary claws respectively. On the one hand, the block-shaped mounting portion can limit the deformation distance of the auxiliary claws on both sides thereof, thereby improving the reliability of the connection between the auxiliary claws and the door and window frames; on the other hand, the main claws and the auxiliary claws form a multi-point clamping fit with the door and window frames, thereby improving the stability of the connection between the drain hole cover and the door and window frames.
